Dr. Marshall made childish, racist and sexist jokes and comments in front of me. He also treated me like a 5 year old, trying to "make me laugh" (presumably) by sticking his pen camera up my nostril and putting the image on the overhead screen for everyone to see. He called me by my last name. He overestimated what "needed" to be done, making it seem like the recommendations he was making were for health, when actually they were only for cosmetic reasons (replacing perfectly good silver fillings with tooth-colored, for example).
